Toall wkome't may concern:

Be it known that I, ELI F. BURCH, a citizen of the United States residing at Laurel Springs, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Lubricating Compounds, of which the following is a full, clear, and exact specification.

This invention relates to lubricating oils, and its object is to produce a lubricating oil which will readily combine with water and form a permanent oily emulsion.

In carrying out my invention, I combine a mineral oil (any suitable neutral mineral oil, but preferably one of the paraflin series) with a soap of a monobasic unsaturated fatty acid, preferably-oleic acid.

As an example, 9% of oleic acid is mixed with 2% of a saturated water solution of borax at a temperature of approximately 100 F. Into this mixture I then introduce 85% of a neutral mineral oil, preferably of the paraflin series, and mechanically stir the mixture. I then add 4% of a saturated alcoholic solution of caustic soda. Under'agitati-on, the mixture clears up into a clear, bright, permanent oily liquid ofapparently colloidal character.

i is used over an r In lieu of caustic soda and borax for effecting the neutralization of the oleic acid, I may employ potash, or other suitable soft soap producing neutralizing agent.

When mixed with water, the liquid forms a permanent emulsion, thus making it especially useful as a lubricant in certain hydraulic machiner inplaces where the water over again, as the fluid serves not only as a lubricant but also as a rust preventative.

Specification of Letters Patent Patentd Nov. 20, 1917. Application filed June 6, 1916. Serial 1T0. 101,950.

Having thus described my invention, I declare that what I claim as new and desire to secure by Letters Patent is:-

1. The process of preparing a lubricant which consists in mixing an unsaturated fatty acid with a water solution of borax, then adding a neutral'mineral oil, then agi tating the mixture mechanically, then adding a saturated alcoholic solution of caustic soda, and furthe: agitating the mixture mechanically until it clears to a bright permanent oily liquid of apparently colloidal character.

2. The process of preparing a lubricant which consists in mixing oleic acid with a water solution of borax, then adding a neutral mineral oil of the parafiin series, then agitating the mixture mechanically, then adding a saturated alcoholic solution of caustic soda, and further agitating the mixture mechanically until it clears to a bright germanent oily liquid of apparently colloial character.

3. The process of preparing a readily emulsifiable lubricant which consists in mixing oleic acid and borax solution, then adding mineral oil, then adding caustic soda,

and agitating the mixture until it resolves ELI F. BURCH.
